Production Process Of Wear-Resistant Steel

 

 

Process Development

In recent years, the surface strengthening technology of steel materials has developed rapidly, and new technologies for the production of wear-resistant steel have emerged.

 

How Wear-Resistant Steel Is Made

Wear-resistant steel is smelted in electric furnaces or converters, and the products are mostly castings. In recent years, forging, rolling and other hot processing materials are increasing. The production method of wear-resistant steel parts used in general machinery is not very different from other workpieces. Only in the heat treatment process or surface treatment process should be required to achieve the need to ensure wear resistance. For those steel parts where the metallurgical purity of the material significantly affects the wear resistance, refining measures should be taken. And the harmful impurities and gas limit requirements. In addition to the matrix, the number, shape and distribution of the second phase often have a significant impact on the wear resistance of steel parts. At this time, it is necessary to consider the design of the chemical composition of steel, smelting, hot processing, heat treatment (including thermomechanical treatment) and so on, in order to strive to achieve the requirements of improving wear resistance from metallurgical factors.

 

Processing Method

1. Through relevant process tests, master the general characteristics and cutting thickness range of various cutting methods of steel plates.

2. Steel plate cutting methods are applicable to cold cutting and thermal cutting. Cold cutting includes water jet cutting, shearing, sawing or abrasive cutting. Thermal cutting includes oxygen-fueled flame cutting ('flame cutting'), isoparticle cutting and laser cutting.

3、Flame cutting of high grade wear resistant steel is as simple as cutting of ordinary low carbon and low alloy steel. When cutting thick plates of wear-resistant steel, it should be noted that as the thickness and hardness of the steel plate increase, the tendency of cracking at the cutting edge increases.

 

How To Enhance Wear Resistance

Different surface strengthening techniques can be chosen to improve the wear resistance of steel parts under various types of wear conditions. Replace expensive alloy steels with less expensive base materials. Carburizing, carbonitriding, nitriding and other processes are still the main measures to strengthen mechanical parts. The use of co-infiltration, compound infiltration, boron infiltration, metal infiltration, spray welding, overlay welding, vapor deposition, electro-brush plating, ion injection and other processes in various working conditions of different parts have achieved significant results in improving wear resistance. In addition, casting processes such as casting infiltration and composite casting are also used in the manufacture of wear-resistant steel parts.

Understanding Abrasion And Wear-Resistant Steel(AR Steel)

Not all steels are the same. In fact, there are more than 3,500 different grades of steel, each containing unique physical, chemical, and mechanical properties to make them "custom-tailor" to suit specific applications. Even in certain steel groups, such as abrasion and wear-resistant steel (AR steel), there are many different grades, each with different chemical and mechanical properties, resulting in different properties.

 

Countless shadows of tough

Each number of these AR steel types refers to the hardness of the steel measured on the Brinell hardness scale. However, the processes used by the manufacturers of these AR steel grades can be very different, using different alloys, chemistries and heat treatments to achieve the specified hardness, yield, tensile strength and elongation of the final product. They are all wear-resistant, they all meet the Brinell hardness requirements, but they are all made by very different methods.

 

What makes steel AR?

AR steel alloy is made of steel billets containing different alloying elements such as carbon, manganese, chromium, nickel and boron. Of all these alloys, carbon is the most important for making steel wear resistant because it increases hardness and toughness. Then AR steel is produced through the "Quenching and Tempering" (Q&T) process, in which the grain structure is changed, the toughness is improved, and the brittleness is reduced.

Q&T is a two-stage process: when steel is brought to about 1500 degrees Fahrenheit and then cooled with oil, water or air, quenching occurs. This process increases the hardness. Tempering is the process of heating steel to approximately 300-700 degrees Fahrenheit, which makes the steel tougher.

 

 

Although the high-carbon alloy and Q&T treatment make the steel harder, it also reduces its tensile strength. Therefore, AR steel is used in situations where wear, abrasion, tearing and impact are the main issues, rather than constant tension or pressure. Therefore, AR steel is not suitable for structural structures such as beams in bridges and buildings. Common uses are in barrels, grilles, chutes, conveyor belts, mine bags, and armored vehicles and targets.

 

Better quenching, better steel

Most AR steels are water quenched because this is the fastest and cheapest option. Other AR steels are quenched by water, which destroys the grains, causing the microstructure to resemble a falling "pick-up sticks", making it more likely to be scratched and torn, and accelerate wear and deforming the steel.

Abrasion resistant steel is a steel material with strong wear resistance containing chemical elements such as silicon, manganese, chromium, copper, vanadium and so on.

Abrasion-resistant (AR) steel plate is a high-carbon alloy steel plate. Due to the addition of alloys, AR has formability and weather resistance. Due to the addition of carbon, its hardness is higher.

Abrasion-Resistant Steel Plates For Long Service Life In Harsh Conditions

Abrasion-Resistant Steel Plates For Long Service Life In Harsh Conditions

Abrasion resistant (AR) steel plate is a specially designed high-carbon alloy steel with greater hardness than low-carbon steel.

Hardness is usually at the expense of strength, which makes AR wear-resistant steel an ideal material for harsh, high-wear conditions, rather than for structural applications.

Unlike many structural steels, AR is not subject to any ASTM codes or specifications, nor does it require specific chemical compositions. In fact, the composition of AR steel varies from mill to mill. On the contrary, hardness (Brinell hardness unit) is the most important factor for engineers when evaluating AR steel plate materials.



What are the benefits of AR steel?

In applications involving impact and/or sliding contact with abrasives, the benefits of using wear-resistant steel plates are huge.

Abrasion resistant steel plates are very durable, wear-resistant, and prevent wear and scratches. This type of steel works well in demanding applications and also provides a certain degree of impact resistance. Wear-resistant steel plates will ultimately help extend the life of your application and reduce your costs in the long run.


Industrial AR steel plate

Abrasion resistant steel plates are widely used in energy, industrial manufacturing, infrastructure and other fields. Other applications include:

How To Specify Hydraulic Hose Fittings

Hydraulic hose fittings connect hoses to pumps, valves, cylinders, and other components used in the entire hydraulic system. These safe connections help control and direct the flow of hydraulic fluid to where it is needed, while preventing leakage and maintaining pressure safely.

Experts say it is beneficial to distinguish hoses from complete hose assemblies. Although the choice of hose is obviously important, choosing a hose without considering accessories can be a costly mistake. Any hose assembly includes accessories for specific applications. Industrial hose assemblies must have hoses, fittings, and methods to connect the fittings to the hoses. For most hydraulic hoses, the fitting has a barbed end, which is inserted into the inner diameter of the hose, and a shell or clamp, which is connected to the cover or reinforcement.

Hydraulic hoses

Crimping is the most common method of assembling hoses and fittings. Once the crimp specifications of the specific hose and accessories are checked, the crimping machine is adjusted to the proper crimp diameter setting. The next step is to lubricate the tube, push it into the end of the hose, and then insert the tube into the crimping die. Start the crimping device, close the mold and permanently compress the fitting onto the hose.

Many companies offer no-skive options on their hoses. Peeling refers to a process in which part of the hose cap or even the inner tube is removed-the reinforcement layer is exposed-before the hose end is connected. No-skive hose does not require this step. Many users prefer the no-slip option because it makes hose assembly faster and reduces the risk of hose damage during crimping.

Therefore, in addition to hoses, users must also choose accessories based on chemical compatibility and connection safety. In addition, it is also necessary to consider the segmentation of the application, such as operating pressure, flow capacity, environmental and temperature extremes, and operating fluids.

When installing the hose assembly, pay attention when determining the thread of the connection. Usually, it is connected from one standard to another standard port, but there is not enough contact to ensure safety. In addition, most of the accessories are certain hoses of a specific brand, and may not cooperate with other brands. Although the size of the joint usually corresponds to the size of the wire, there may still be differences in the choice of joints for the same size hose.

For safe and durable hydraulic components, the "correct" components are couplings, hoses, crimping equipment and accessories, which are designed to work together. Tolerances vary from manufacturer to manufacturer and are not interchangeable. Different components from different manufacturers may adversely affect the coupling retention. Accidental mixing and matching may cause hose rupture, joint leakage and blow-out ends, injuring or even killing workers.

Introduction Of Abrasion-Resistant Steel Plate (AR plate)

What is AR plate?

Abrasion-resistant steel plate (AR plate) is a special plate product of high-carbon alloy steel plate, which is mainly used for work that will produce large-area wear. Wear-resistant steel plates are welded on the surface of low-carbon steel or low-alloy steel to form one or more layers of alloys with higher hardness, weather resistance and higher wear resistance, and have better plasticity and toughness. The thickness of this alloy wear-resistant layer is generally 1/3 ~ 1/2. It is adding carbon, manganese, nickel, chromium, boron and other alloys to the steel plate to relatively increase the hardness and toughness of the steel plate. Adding carbon can increase the hardness of the steel plate, but if we add too much carbon to the steel plate, it will become brittle and reduce the tensile strength.

Commonly used in:

Because the wear resistant plate mainly has high wear resistance and good impact performance, it is suitable for welding, cutting, bending, etc. From the point of view of its material, the cost performance is very high, so it has been welcomed by the public in recent years. It is widely used in industrial fields with more extreme environments, such as heavy industrial equipment, mining, electric power, agriculture, construction, and cement industries. This kind of wear-resistant steel plate is very convenient and time-saving in the repair process.

AR plate characteristics

The advantages of wear-resistant steel plates are as follows:

1) Good wear resistance

The wear-resistant steel plate has a layer of alloy wear-resistant layer on the outside, and the composition of this layer of alloy wear-resistant layer contains chemical elements such as carbon and chromium, making it twice the hardness and wear resistance of ordinary steel plates.

2) Strong impact resistance

According to what we mentioned above, there are mainly two layers of wear-resistant steel plates, the base material is low-carbon steel or low-alloy steel plate and a layer of alloy wear-resistant layer. The outer alloy wear-resistant layer can be used to resist the wear of the wear medium, and the inner base material can withstand the load of the medium, so as to achieve good impact resistance. At the same time, it can withstand the impact and abrasion of the high drop hopper in the material conveying system.

3) Good heat resistance

Adding vanadium, molybdenum and other alloys to the alloy wear-resistant layer can increase the heating degree of the steel plate. Approximately can withstand high temperature wear ≤800℃.

4) Superior corrosion resistance

Since the alloy layer of the wear-resistant composite steel plate contains a large amount of metallic chromium, it has good rust and corrosion resistance.

5) Convenient processing performance

The wear-resistant steel plate can be processed into various industrial parts through cutting, bending, welding, etc. according to the needs of the project.

Abrasion-resistant steel plates have higher hardness than ordinary steel plates, and have stronger wear resistance and corrosion resistance.

What Is Wear-Resistant Steel Plate?

 In manufacturing and construction, the composition and grade of the steel plate material used have a huge impact on the final product. Abrasion resistant steel plate is an ordinary steel plate with harder quality. Compared with ordinary high-strength structural steel plate, the durability time is about 4 times.

However, what makes it stronger, and how do you know when a project needs wear-resistant steel?

What is wear-resistant steel plate?

Abrasion-resistant (AR) steel plate is a high-carbon alloy steel plate. Due to the addition of alloys, AR has formability and weather resistance. Due to the addition of carbon, its hardness is higher.

The addition of carbon during the formation of the steel plate significantly increases the hardness and toughness of the steel plate, but the strength decreases. Therefore, AR plates are used under conditions where wear and abrasion are the main causes of failure. AR plates are not perfect in structural construction applications, such as supporting beams in buildings or bridges.

Common applications for AR plates include dump truck liners, grates, buckets, construction accessories, conveyor belts, body armor and ballistic panels (and as targets for shooting ranges).

How is abrasion-resistant steel made?

The main alloying elements of abrasion-resistant steel are iron (Fe) and carbon (C), although various low-content and trace minerals are added to adjust the chemical and mechanical properties of the final product. First, the raw iron is melted in a blast furnace, and then carbon is added to the melt. Depending on the application area, additional elements such as silicon (Si), nickel (Ni) and molybdenum (Mo) can be added at this stage. Abrasion-resistant steels can contain as much as 0.18-0.30% carbon, and they are medium and low carbon steels.

Once the proper composition is reached, the molten mixture is formed and cut to the proper size. Wear-resistant steel is generally not suitable for quenching and tempering because heat treatment has the risk of reducing material strength and wear resistant properties.

The wear resistance qualities of the abrasion-resistant steel alloy is obtained by strictly controlling the basic mechanical properties of the material. The most important of these are:

Hardness (Brinell hardness), which determines the ability of the material to withstand impact.

Strength (yield and tensile), which determines the structural integrity of the material under high loads.

Abrasion is used to define any process in which the surface of a material wears away due to friction. This may occur where the surface is worn, scratched, or gradually worn out in contact with other parts or materials. This is a common problem in heavy industry, but it can also be a problem for more complex machinery associated with high duty cycles or challenging operating conditions. The solution to this phenomenon is to maintain adequate lubrication of the mating surface, or use suitable wear-resistant materials to optimize performance.

Abrasion resistant steel is an optimized alloy that can withstand surface wear, which can lead to a series of unexpected consequences, from simple aesthetic damage to complete structural damage.
